In addition to being an almost infinite repository of information, Internet offers vast resources for research, communication and dissemination of information. Taking profit of the potential offered by this means, we examine ways of accessing information over the Internet to find information and evaluate its quality and relevance to the educational process. This will address issues on source credibility and copyright. As far as communication is concerned, it will be analysed synchronous and asynchronous tools, techniques and possibilities of using email, newsgroups and mailing lists, forums, chats and instant messengers and evaluate its importance in educational processes. A central aspect of the research is sharing results and therefore some procedures relevant to their publication on the network will be reviewed.
